Basic terms
Understanding
Understanding is one of the most important
human capabilities that plays a key role in all
human activities. In understanding of the visual forms - two main processes
are distinguished: one that handles perceptual organization and facilitates
rapid visual identification, and the second that manages semantic
categorization. In the shape understanding method an object is interpreted
as a meaningful unit called a phantom.
A phantom’s meaning is its
ability to invoke content. A phantom’s meaning can be seen as coming from
our shared experience of objects or from a sign convention.
A Phantom – the 2-D visual object ( e.g. a letter, a sign, a drawing, a photograph).
An
Archetype – an ideal shape representation in the 2-D Euclidean space.
An Exemplar - a digital
representation of an archetype in the discrete space.
SUS is
given, as an input, the digital object and during reasoning stages SUS
assign an examined
object to one of the shape classes.
In the
shape understanding method the meaning of the phantom is given by three
components:
a phenomenal concept, a metalingual
concept, and a visual concept. The visual concept shows the
subjective way in which a given phantom is seen. The visual
concept is given as a set of symbolic
names
An example – a visual
representation of an arrow.
Visual concept of the
